Gene regulation in Eukaryotes for the formation of proteins takes place at the following levels.
I. Transcriptional level
II. Splicing of hnRNA
III. mRNA transport from nucleus to cytoplasm
IV. Translation level
In Eukaryotes, gene regulation for the formation of proteins takes place at transcription level by regulatory sequences of transcriptional units, Splicing level by spliceosomes, capping enzymes and tailing enzymes and transport of mRNA through nuclear pores and during translation by various protein factors and enzymes.
